| 摘 要： | We present world average values for D~0-~0 mixing parameters x and y,CP violation parameters |q/P|and Arg(q/p),and strong phase differencesδandδ_(Kππ)These values are calculated by the Heavy Flavor Averaging Group(HFAG)by performing a global fit to relevant experimental measurements.The results for x and y differ significantly from zero and are inconsistent with no mixing at the level of 6.7a.The results for |q/P|and Arg(q/p)are consistent with no CP violation.The strong phase differenceδis less than 45°at 95%C.L.
